PROCESS OF COLORING AND FINISHING FABRICS.

SPECIFICATION forming part of Letters Patent No. 449,104, dated March 31, 1891.

Application filed October 18,1888. Serial No. 238,476- (No specimens.)

citizen of the United States, and a resident of the city of Baltimore and State of Maryland, have invented a certain new and useful Process for Coloring and Improving the Finish and Durability of Yarn and Fabrics, of which the following is a specification.

There is a large class of goods now upon the market known as hollands, hollenas, book-cloths, &c., which are used for shadecloths, book-covers, and other similar purposes, and which are sized and finished with starch. These goods are of such a character that when they become moist the sizing and finish of the goods isinj ured. Adrop of water or the condensation of moisture upon such goods renders them unsightly and obj ectionable by staining them or removing the color and finish.

The object of my invention is to overcome these objections by rendering the starch contained in these starched, sized, or filled goods insoluble without injuring the fiber or fabric. I have discovered that the starch with which these goods are sized may be rendered insoluble in several different ways, thereby producing goods the finish and appearance of which will not be affected by water. The starched or filled cloth prepared by my method may be even cleansed by sponging it with water without injury to the appearance or finish.

In carrying out my invention I take a white or colored fabric that has been sized or filled with starch and pass it through or subject it to the action of a solution (either hot or cold, as may be found most desirable) of any compound or substance which by its chemical action will render the starch insoluble. Among the substances used for this purpose may be named caustic lime and other lime compounds, caustic baryta, basic salts of iron,

alkaline compounds of lead, and many other substances, for which reason I do not intend to limit myself to any one of these substances or classes, any one or more of which I intend to use according to the characterof the goods operated upon and the effect desired. The invention which is the subject of this application may also be employed for the purpose of permanently fixing the coloring on fabrics. To accomplish this purpose, either soluble or insoluble color is added to a thin solution of starch. The fabric is then passed through or padded with this mixture and, preferably, after being dried is passed through a bath or compound which has the power of rendering the starch insoluble, such as above mentioned, and thus the color is permanently fixed by means of an agglutinative little if at all inferior to albumen.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The herein-described process of improving the durability and permanency of the finish or color, or both, of a starched fabric or yarn by treating the starched fabric or yarn with a solution of caustic lime or other equivalent compound which has the power of rendering the starch insoluble.

2. The method herein described of finishing or coloring and finishing fabrics, which consists of applying to or impregnating the fab ric with starchor amixture of starch and coloring-matter, and then treating the fabric thus impregnated with a solution of caustic lime or other equivalent compound, which has the power of rendering the starch insoluble.
